Nysc: What's The Process?

So I understand if you school outside of Nigeria, you get to choose where you serve. Some people say its not true and on the official NYSC site, they say you dont get to choose. My friend just went back though and she's starting with this set (September I think). She says she was allowed to choose between Lagos and Abuja. So I guess sometimes they allow and sometimes they dont, cos another friend, he starts in February next year and they wont allow him choose, so he's being flung to some state in the north.

Anyhow, I'd like to know: After camp, or before camp, what happens? I remember there was a time when you went to look for a job and then a company of your choice employed you and you went back to register this company as your place of work with the NYSC (my brother had it this way like 8yrs ago I think or 10 yrs ago).

Could anyone tell me how it works. Hope they dont just throw you to teach in some remote village? Do they still do that? Cos its the reason Im dragging out on my BA until Im 30 years old so I dont have to do that NYSC thing. It sounds stressful and unecessary.

Oh thanks a lot for the info.
If its possible to get a company to write nysc and tell them they need me, then Im sooo going to work towards that, cos I cant get thrown to some remote place and waste a whole year of my life lol.
Thanks once again
